RE: Cart and Horse

Wouldn't some authentication system be more useful than trying to lock all the manholes? Picture a system maybe using RFID or some other radio system where you walk up to manhole, wave your 'wand' (like a Mobil Speedpass), you hear a couple beeps, and you're cleared to open the manhole. Without

IP DSLAMs

All, Looking for a recommendation on DSLAMs to replace our unsupported Cisco 6015s. Requirements are: G.SHDSL 2 and 4 wire mode (CPEs are strictly Cisco 828, 878, and small cisco routers using WIC-1SHDSL and the V2/V3 of them) QOS would be nice, not a necessity SNMPv3 and SSHv2 support

RE: What's with all the long aspaths?

Sounds like some automated scripts that didn't do any sanity checking. Process pulls the current BGP table, checks for the longest path, and then prepends the AS that many times to guarantee everyone takes the other path. But if two ISPs are doing this, well, the paths get longer and longer. I
